What Is Satellite Dish?
A Satellite Dish Is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit.
The primary function of a satellite dish is to convert microwave signals into electric signals that can be used by a computer, television and other devices. The low-frequency signals can be received by the larger dishes, whereas small dishes are used for higher frequency signals.
There Are Three Basic Types Of Satellite Dishes:
- Motor Driven Satellite dishes: Configured with a stepper motor. These can be controlled from the sky and moved to a suitable position according to a satellite position.
- Multi-Satellite dishes: Support multiple reflectors that enable them to receive signals from multiple locations simultaneously. The additional reflectors are placed vertically to capture all the signals that are originated from different locations.
- Very Small Aperture Terminal (VSAT) dishes: Employed for both consumer networks and private network operations. VSAT is most commonly used satellite dish in the world.
What Is A Satellite Dish Used For?
Parabolic microwave antenna used to transmit and receive satellite signals. On the downlink, the dish collects data or video signals from orbiting satellites and focuses them to where a feed horn collects them and passes the signal on to be amplified and sent to a satellite receiver or IRD.
How Does Satellite Dish Work?
A satellite dish works in the same way as the reflector for a torch or car headlights. A signal is produced or reflected from a focal point. This signal then reflects off the large part of the satellite dish and travels towards the satellite.
The working principles behind satellite dishes are as simple as a conventional cable connection. A satellite transmitter is used to send the signals through the air to bounce them off to a satellite. These signals can then be received anywhere in the world with the help of receivers attached to satellite dishes.
